Sport fisheries of lakes are embedded in complex system of ecological and social interactions. The multiple drivers that affect lake sport fisheries, along with the complex interactions within lakes, make it difficult to forecast changes in sport fisheries and plan adaptive responses to build resilience of these important resources. Resilience involves managing with an eye toward critical thresholds for behavior of ecosystems. Project researchers are working to develop quantitative tools for assessment of thresholds in sport fisheries that can be used by management agencies to evaluate potential impacts of climate change mediated through species and habitat interactions. Several outputs of the project will be adaptable...
Rivers, wetlands, lakes, and other freshwater ecosystems collectively cover only 1% of the Earth's surface. Yet, these ecosystems support a disproportionately large and vast array of biodiversity. Currently, these ecosystems face many threats, including pollution, habitat alteration, fragmentation, invasive species, overexploitation, overabstraction, climate change, and other emerging stressors. According to the World Wide Fund for Nature's Living Planet Index, freshwater ecosystems and biodiversity are considered among the most threatened on the planet, with average declines of approximately 83% in the populations of freshwater organisms since 1970. Such losses are impactful not only from a fundamental biodiversity...

Global change, including large scale changes in climate, land use, hydrology, and biogeochemistry, creates unprecedented pressure on inland recreational fisheries. Local fishery managers have little influence on these large-scale changes, but they can manipulate factors such as harvest, food web structure, and some features of habitat. The Safe Operating Space (SOS) concept establishes a framework for analyzing a fishery in the context of both large-scale and local factors. Adaptation is the manipulation of local factors (such as harvest, food web structure, or habitat) to maintain the SOS of a fishery as the climate changes. At the scale of many lakes on a landscape, the SOS can be used to identify lakes that are...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
